[mvapich-discuss] mvapich2 and Intel MPI Benchmarks

[Bryan Putnam]

Hi All,

I just wondered if you'd had a chance to try out the Intel MPI Benchmarks 
with mvapich2. IMB-3.2 is what I'm currently running.

We've had no problems with the latest mpich2-1.1.1p1, however when using 
mvapich2-1.4rc2 or mvapich2-1.4rc1 (on both our IB and iWARP clusters) 
the benchmarks are failing, for example even a simple

mpiexec -np 8 ./IMB-MPI1

will result in errors such as


rank 6 in job 1  coates-a279.rcac.purdue.edu_51100   caused collective 
abort of all ranks
  exit status of rank 6: killed by signal 9 
rank 5 in job 1  coates-a279.rcac.purdue.edu_51100   caused collective 
abort of all ranks
  exit status of rank 5: killed by signal 11 
rank 4 in job 1  coates-a279.rcac.purdue.edu_51100   caused collective 
abort of all ranks
  exit status of rank 4: killed by signal 11 
rank 3 in job 1  coates-a279.rcac.purdue.edu_51100   caused collective 
abort of all ranks
  exit status of rank 3: killed by signal 11 
rank 2 in job 1  coates-a279.rcac.purdue.edu_51100   caused collective 
abort of all ranks
  exit status of rank 2: kille



Thanks,
Bryan
